Clustering?

Is it possible that my baby is cluster feeding at 9 weeks? She’s been extra fussy the past few days and has been spitting up a lot, and then seems to want to feed. She cries and the only thing that calms her down is the boob, even if she already ate 2 hours ago. I’m not sure if she’s spitting it all up and then her stomach is empty again or what is happening..... ftm and don’t know what to do
